are aliens real?

Question

My friend says there real

Answer 1

no! there not real

Answer 2

Aliens are demons here to take our eyes off of God. I read a book called "Alien Obsession" that showed how so many alien abductees come back with instructions from the "aliens" to get involved in witchcraft or new age religions. Their messages were always anti-God. Plus, you notice how so many people give us "the answer" on how to live peacefully? Jesus already gave us that and we didn't listen. Why would we listen to aliens??

Answer 3

When I lived in the USA for three years with my American wife, I had to carry a 'green card' stating that I was an alien. I don't know if other countries make you do this. It's a bit unsettling.

Answer 4

Aliens are definitely real. It's just...not what we think. If you are looking for sentient life, good luck. It is probably in some indistinct galaxy some twenty gazillion light years away, and we will never meet them. However, there is definitely life elsewhere in the universe. They are looking at the moon Europa for life, because they believe that extremophiles may live in its methane oceans.

Answer 5

SETI is close to finding them. Extraterrestrial life is life that may exist and originate outside the planet Earth, the only place in the universe currently known to support life. Its existence is currently purely hypothetical as there is yet no evidence of any other planets that can support life, or actual extraterrestrial life that has been widely accepted by the scientific community. Most scientists believe that if extraterrestrial life exists, its evolution occurred independently, in different places. An alternative hypothesis, held by a minority, is panspermia. This suggests that life could have been created elsewhere and spread across the universe, between habitable planets. These two hypotheses are not mutually exclusive. The putative study and theorisation of extraterrestrial life is known as astrobiology or xenobiology. Speculative forms of extraterrestrial life range from sapient beings, to life at the scale of bacteria.

Many bodies in the Solar System have been suggested as being likely to contain conventional organic life. The most commonly suggested ones are listed below; of these, three of the five are moons, and are thought to have large bodies of underground liquid, where life may have evolved in a similar fashion to deep sea vents.

* Mars - Liquid water is widely thought to have existed on Mars in the past and there may still be liquid water beneath the surface. Methane was found in the atmosphere of Mars. Recent photographs from Mars Global Surveyor show evidence of recent (within 10 years) flows of a liquid on the Red Planet's frigid surface. There is however uncertainty as to whether this was liquid water or CO2 Main article: Life on Mars
* Europa- Europa contains liquid water beneath its 100-mile ice layer, vents on the bottom of the ocean warm the ice so that 60 miles of liquid exist beneath the ice layer, perhaps capable of supporting microbes and simple plants
* Jupiter- Possible supporter of floating animals, as hypothesized by Carl Sagan. This point of view is somewhat controversial due to the fact that these creatures would not be water-based, but ammonia-based.
* Ganymede - Possible underground ocean
* Callisto - Possible underground ocean
* Saturn - Possible floating creatures
* Titan (Saturn's largest moon) - The only known moon with a significant atmosphere was recently visited by the Huygens probe. Latest discoveries indicate that there is no global or widespread ocean, but small and/or seasonal liquid hydrocarbon lakes are almost surely present on the surface.

Numerous other bodies have been suggested as potential hosts for microbial life. Fred Hoyle has proposed that life might exist on comets, as some Earth microbes managed to survive on a lunar probe for many years. However, it is considered highly unlikely that complex multicellular organisms of the conventional chemistry of terrestrial life (animals, plants) could exist under these living conditions.

Answer 6

About as real as Batman and Superman. Or anything in Marvel Comics. The only place they ever really existed.

Answer 7

In theory, yes. The Drake Equation, crafted in 1961, proposes a mathematical formula by which the number of intelligent species might be estimated:

(The following text is from http://www.setileague.org/general/drake.htm)

N = R* fp ne fl fi fc L

where,

N = The number of communicative civilizations
R* = The rate of formation of suitable stars (stars such as our Sun)
fp = The fraction of those stars with planets. (Current evidence indicates that planetary systems may be common for stars like the Sun.)
ne = The number of Earth-like worlds per planetary system
fl = The fraction of those Earth-like planets where life actually develops
fi = The fraction of life sites where intelligence develops
fc = The fraction of communicative planets (those on which electromagnetic communications technology develops)
L = The "lifetime" of communicating civilizations

Frank Drake's own current solution to the Drake Equation estimates 10,000 communicative civilizations in the Milky Way.

(End quoted text.)

So, that's a lot of potential interstellar neighbors. The issue comes in differences in communication between species and the currently-unresolved problem of light as the ultimate speed limit.

Einstein's researches seem to imply that nothing can exceed the speed of light, and that an object approaching lightspeed becomes more massive, suffers from temporal distortions, etc.

The long and the short is that nothing can apparently exceed the speed of light, and space is so large. It would take incredibly advanced technologies (or very long-lived aliens) to bridge the gulfs between the stars, and it implies an expenditure of time and resources that would be considerable no matter who was making the trip.

How we would communicate with intelligent aliens is another problem. We assume in science fiction that their communicative abilities would be similar to ours and that they would wish to convey thoughts similar to our own. This is patently unworkable when one considers a truly alien species, however. Lifeforms made of silicon, for example, would have an almost completely different view of the cosmos and a completely different interaction with it than we would. Those differences in cognitive experience, as well as the obvious barrier of language if such was employed in any manner by the aliens in question, underscore the vast difficulty of effectively conveying anything of note to an alien species.

So the fundamental questions are:

- How many species are there? Utterly unknown, and Drake's equation has come under some criticism because of its reliance on utterly unknown variables.

- How can we see them? We can't, at least in a normal human lifetime, if Einstein's theories are correct. If we could travel at the speed of light, it would take four years to reach our nearest stellar neighbor. But we can't travel anywhere that fast.

Consider the following, from Wikipedia:

"The nearest known planetary system to the Sun is known as Epsilon Eridani, which is 10.3 light years away. Voyager 1 is traveling at nearly 0.00558% the speed of light as it leaves our solar system. Currently, the fastest spacecraft built can achieve a velocity of about 77.3 km per second or 0.025% the speed of light relative to Earth. At that rate, the journey would take about 50,245 years. Additionally, at the current stage of space technology, the longest space missions that have been initiated are expected to have an operational lifetime of about 63 years before failure of key components is likely to happen. Significant engineering advances such as automated self-repair may be required to ensure survival."

Not very promising, at least at this stage of technological development. Certainly, there could be beings that might be advanced enough to travel at near lightspeed, but even then the vast gulfs between stars are considerable, especially if Einstein's speed limit holds.

- Could we communicate if we found one another? These beings, rather than the slightly skewed hominids of science fiction, would be truly alien. Communication might prove difficult if in not impossible, especially at first. Consider beings that communicate through chemoluminescence, chemical color changes, or through raising and lowering ambient temperature, or species-specific telepathy, or ... whatever.

Answer 8

I look at it this way; Jodi Foster said, in the movie Contact, something like, if we are the only living beings, anywhere...it seems like an awful waste of space.

Answer 9

yes go to california and see all the aliens

Answer 10

If you watch the night skies enough, eventually you will see something that moves noiseless and makes right angle turns at very high speed.

Answer 11

no people are just looking for God not aliens
